Feem ntau hais lus, nyob rau hauv thiaj li yuav tau txais cov khoom siv tshuab hluav taws xob ntau dua, qhov ntsuas kub siab dua yuav tsum raug xaiv. Txawm li cas los xij, rau 6063 alloy, thaum qhov kev tiv thaiv qhov kub thiab txias tshaj li 540 ° C, cov cuab yeej siv qis dua 480 ° C, lub zog tensile yuav tsis muaj zog.
Yog tias qhov ntsuas kub ua kom sov dhau heev, cov npuas, tawg, thiab cov pob txha thiab txawm tawg yuav tshwm sim ntawm cov khoom vim cov pwm. Yog li ntawd, txhawm rau txais cov khoom lag luam nrog cov khoom siab zoo, kuj muaj qhov tsis kub thiab txias siv tau.
Cov khoom siv zoo kuj yog taw tes tseem ceeb los txhim kho kev ua haujlwm ntawm txhuas ntawm txhuas extruder, txhuas qws cua sov cua sov, thiab cov tshuab cua sov, thiab cua sov cua sov Tsis tas li ntawd, qhov tseem ceeb tshaj plaws yog kom muaj ib tug zoo tshaj plaws Extrus tus neeg ua haujlwm.
Kev ntsuas cua sov
Aluminium tuav thiab cov pas nrig yuav tsum tau ua ntej-rhuab ua ntej extrusion kom mus txog qhov kub thiab txias nyob rau hauv aluminium pas tuaj yeem yaj thiab ntws tusyees hauv cov khoom siv txhuas. Thaum tus pas nrig txhuas tau muab tso rau hauv Extruder, qhov kub tsis hloov pauv ntau.
Thaum tus Extruder pib, lub zog loj ntawm extruding pas nrig thawb kev sib txhuam, yog li qhov kub ntawm extruded profile tshaj li cov solvus kub. Nyob rau lub sijhawm no, cov magnesium melts thiab ntws ib ncig, uas yog qhov tsis ruaj khov.
Thaum qhov ntsuas kub tau tsa, nws yuav tsum tsis yog siab dua li cov solidus kub, txwv tsis pub tus txhuas kuj tseem yuav yaj, thiab cov ntaub ntawv tsis tuaj yeem tsim. Noj 6000 series alloy raws li ib qho piv txwv, Aluminium Rod kub yuav tsum tau muab khaws cia ntawm 400-540 ° C, nyiam 470-500 ° C.
Yog tias qhov ntsuas kub siab dhau lawm, nws yuav ua kua muag, nws yog qhov qis dhau, thiab feem ntau ntawm cov kev sib txhuam tsim los ntawm kev rho tawm ua cua sov, ua rau qhov kub kom nce. Qhov ntsuas kub nce yog sib npaug rau cov extrusion ceev thiab extrusion siab.
Lub qhov hluav taws xob kub yuav tsum tau nyob hauv 550-575 ° C, tsawg kawg ntawm 500-530 ° C, tsawg kawg ntawm cov hlau nplaum hauv cov khoom siv hlau. Tab sis nws yuav tsum tsis yog siab dua li cov solidus kub, loj dhau qhov hluav taws xob yuav ua rau lub ntsej muag thiab cuam tshuam rau qhov zoo ntawm qhov profile.
Qhov zoo heev extrusion kub ntawm aluminium pas dej yuav tsum tau hloov kho kom sib txawv yog li ntawd qhov sib txawv qhov sib txawv tsis qis dua cov solvus kub thiab tsis siab tshaj qhov ntsuas kub. Cov alloys sib txawv muaj cov solvus sib txawv. Piv txwv li, cov solvus kub ntawm 6063 alloy yog 498 ° C, thaum lub sij hawm ntawm 6005 alloy yog 510 ° C.
Tsheb Laij Teb Ceev
Tsheb laij teb ceev yog qhov ntsuas tseem ceeb ntawm kev ua tau zoo. Txawm li cas los xij, cov ntawv sib txawv, cov duab sib txawv, cov duab, ntau thiab lwm yam yuav cuam tshuam rau kev ceev ntawm lub tsheb laij teb, uas tsis tuaj yeem yog dav dav. Niaj hnub nimno Western Extrusion Cov ntsiab lus Factories tuaj yeem ua tiav ib lub tsheb laij teb ceev ntawm 80 meters ib feeb.
Extrusion pas nrig tus nqi yog lwm qhov ntsuas tseem ceeb ntawm cov khoom lag luam. Nws yog ntsuas hauv cov millimeters ib feeb thiab extrusion pas dej ceev yog feem ntau txhim khu kev tshaj plaws ntau dua li cov tsheb laij teb ceev thaum kawm ntau lawm.
Pwm kub yog qhov tseem ceeb heev rau qhov zoo ntawm extruded profiles. Pwm txias yuav tsum tau khaws cia ntawm kwv yees li 426 ° C ua ntej extrusion, txwv tsis pub nws yuav yooj yim txhaws lossis txawm puas cach lossis txawm tias puas muaj pwm. Lub hom phiaj ntawm quenching yog kom "khov" lub alloying magnesium, ruaj khov qhov tsis ruaj khov magnesable magnesable magnesages mods thiab tiv thaiv lawv los ntawm kev daws teeb meem, txhawm rau tswj lub zog ntawm qhov profile.
Peb lub ntsiab lus tseem ceeb quenching suav nrog: huab cua txias, dej ua rau cua txias, dej kiv cua txias. Cov hom quenching siv yog nyob ntawm qhov extrusion ceev, cov tuab thiab cov khoom siv lub cev xav tau ntawm cov ntaub ntawv, tshwj xeeb yog cov muaj zog yuav tsum tau ua. Hom Alloy yog qhov qhia tau zoo ntawm lub hardness thiab elastic muaj zog ntawm cov alloy. Txhuas Alloy hom tau teev nyob rau hauv kev nthuav dav los ntawm American Alternation, thiab muaj tsib qhov pib:
F txhais tau tias "ua ntaub qhwv".
O txhais tau tias "annealed wrought khoom".
T txhais tau tias nws tau "kho cua sov".
W txhais tau tias cov khoom tau raug tshuaj kho cua sov.
H yog hais txog tsis yog cov khoom siv kho cua sov uas yog "ua haujlwm txias" lossis "plual hardened".
Qhov kub thiab txias thiab lub sijhawm yog ob qho ntsuas uas xav tau kev tswj hwm nruj me ntsis. Nyob rau hauv cov khoom siv artificial wreaking, txhua feem ntawm qhov kub yuav tsum yog tib yam. Txawm hais tias tsawg tus mob kub tuaj yeem txhim kho lub zog ntawm cov profiles, lub sijhawm yuav tsum tau nce raws li. Txhawm rau kom ua tiav cov khoom siv tawv hlau zoo tshaj plaws, nws yog qhov tsim nyog los xaiv cov kev ua kom haumxeeb, siv cov txiaj ntsig kev ua kom zoo, siv cov txiaj ntsig kev ua kom zoo, siv yog lwm qhov tseem ceeb tshaj plaws ntawm kev tsim khoom efficiency. Nws yog theoretically tsis yooj yim sua kom ua tiav 100% tawm los, vim hais tias cov tab sis yog txiav tawm cov khoom vim lub pinch thiab tsab caj qaum.
